+Sometimes when you are importing from a module, you would like to know whether
+a modules function is being used as an import, or if you are using the original
+.py file of that module. In this case we can use the:
+
+      if __name__ == "__main__":
+
+line to determine this. For example:
+
+When your script is run by passing it as a command to the Python interpreter:
+
+    python myscript.py
+
+all of the code that is at indentation level 0 gets executed. Functions and
+classes that are defined are, well, defined, but none of their code gets ran.
+Unlike other languages, there's no main() function that gets run automatically
+- the main() function is implicitly all the code at the top level.
+
+In this case, the top-level code is an if block.  __name__ is a built-in variable
+ which evaluate to the name of the current module. However, if a module is being
+ run directly (as in myscript.py above), then __name__ instead is set to the
+ string "__main__". Thus, you can test whether your script is being run directly
+  or being imported by something else by testing
+
+    if __name__ == "__main__":
+        ...
+
+If that code is being imported into another module, the various function and
+class definitions will be imported, but the main() code won't get run. As a
+basic example, consider the following two scripts:
+
+    # file one.py
+    def func():
+        print("func() in one.py")
+
+    print("top-level in one.py")
+
+    if __name__ == "__main__":
+        print("one.py is being run directly")
+    else:
+        print("one.py is being imported into another module")
+
+and then:
+
+    # file two.py
+    import one
+
+    print("top-level in two.py")
+    one.func()
+
+    if __name__ == "__main__":
+        print("two.py is being run directly")
+    else:
+        print("two.py is being imported into another module")
+
+Now, if you invoke the interpreter as
+
+    python one.py
+
+The output will be
+
+    top-level in one.py
+
+one.py is being run directly
+If you run two.py instead:
+
+    python two.py
+
+You get
+
+  top-level in one.py
+  one.py is being imported into another module
+  top-level in two.py
+  func() in one.py
+  two.py is being run directly
+  
+Thus, when module one gets loaded, its __name__ equals "one" instead of __main__.
